Each galaxy is a collection of billions of stars; we have no idea if there are any life forms on the planets around those other stars, perhaps looking at OUR galaxy and asking "What is the purpose of all the other galaxies?"
Everything that is created has a purpose by the Creator:
Gen 1:16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: [he made] the stars also.
Psa 147:4 He telleth the number of the stars; he calleth them all by [their] names.
Deu 1:8 Behold, I have set the land before you: go in and possess the land which the LORD sware unto your fathers, Abraham, Isaac, and Jacob, to give unto them and to their seed after them.
Deu 1:10 The LORD your God hath multiplied you, and, behold, ye [are] this day as the stars of heaven for multitude.
Psa 8:4 What is man, that thou art mindful of him? and the son of man, that thou visitest him?
Hbr 2:7 Thou madest him a little lower than the angels; thou crownedst him with glory and honour, and didst set him over the works of thy hands:
Hbr 2:8 Thou hast put 'all things' in subjection under his feet. For in that he put all in subjection under him, he left nothing [that is] not put under him. But now we see not yet all things put under him.
1Cr 15:51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
1Cr 15:52 In a moment, in the twinkling of an eye, at the last trump: for the Trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
1Cr 15:53 For this corruptible must put on incorruption, and this mortal [must] put on immortality.
1Cr 15:54 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
Rev 22:4 And they shall see his face; and his name [shall be] in their foreheads.
Rev 22:5 And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.
We expect the Andromeda galaxy to be just like our own Milky Way galaxy. We can see stars (suns) in the Andromeda Galaxy and just as stars have planets orbiting them in our galaxy, we believe that there must be planets also orbiting stars in the Andromeda galaxy.
A galaxy is a huge group of stars that form a spreading spiral. Our own Milky Way galaxy is an example of a spiral galaxy.
A group of stars, gas, and dust held together by gravity is known as a galaxy. Galaxies come in various shapes and sizes and can contain billions to trillions of stars. Our own galaxy, the Milky Way, is a spiral galaxy containing around 100-400 billion stars. The gravitational forces within a galaxy keep its components bound together in a cohesive structure.

This small galaxy likely has a relatively low amount of gas and dust, resulting in fewer new stars being formed. The older stars in the galaxy may dominate the population, giving it a more mature appearance. The lack of dust can also lead to clearer observations of the stars within the galaxy.
Generally stars will stay within a galaxy for their whole existence. However, stars toward the edge may succumb to gravitational attraction from other objects outside of the galaxy. Also, galaxies do "merge" with each other and during that process stars may well be "shot" off out of the galaxy. These processes are rare (in our lifetime), so you could say that the question is true.
A galaxy is by a definition a group of stars. If there were no stars it could not be a galaxy.
Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
Elliptical Galaxy The Elliptical Galaxy has mostly old stars and blue stars are new stars.
Im not sure I understand your question fully, but stars don't stay in one place. They are, in fact, revolving around the centre of the galaxy (which is an enourmous black hole)
If it didn't have stars it wouldn't be a galaxy
The answer is Galaxy. a circular collection of stars is a galaxy
There are about 200 -> 400 billion stars in our Galaxy
the milky way is everybodys galaxy and yes the stars you see are in your galaxy
Yes, stars can exist outside of a galaxy. These stars are typically referred to as intergalactic stars, and they may have been ejected from their original galaxy due to interactions with other stars or galactic dynamics. Intergalactic stars are typically found in the space between galaxies.
It means that a galaxy is made up of millions or billions of stars.
